Title: Architectural motor-driven opening/closing device
Inventor: TOKUYAMA NORIAKI
IPC: E06B9/72
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To improve load detecting and obstacle detecting accuracy by forming an electric motor main body or a motor motive power transmission member as a displacing member displaced according to a load change, holding this displacing member in a neutral position by a neutral holding spring, and detecting a displacement quantity of the displacing member against this spring by sensors. SOLUTION: A winding drum 2 balances a load of a shutter curtain increasing as it lowers by energizing force of a balance spring 9, and opens/closes the shutter curtain on the basis of reciprocal driving of an electric motor 11 to share its difference. Here, an almost U-shaped neutral holding spring 30 interposed between a rear side motor holder and a rear side motor bracket 22, elastically holds the electric motor 11 supported so as to be freely rotatable/ displaceable in an almost intermediate position of its rotational range, and the electric motor 11 is displaced in rotation against the neutral holding spring 30 by a quantity according to a load. A control panel 34 arranged in a lower part of a winding shaft 6 detects this rotational displacement angle by a pair of limit switches (displacement sensors).

Title: Tube cover in automatically extensible gate door
Inventor: IKEMIZU MAKOTO
IPC: E05F15/14
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent a tube cover from sagging down near the middle part thereof. SOLUTION: The distance between both ends of a tube cover 11A is constituted so that the upper side at the time when it is fitted to a frame, becomes smaller than the lower side. As a result, the fitting 110 of both ends of the tube cover 11A is fitted to the frame so that the upper side distance A between both ends becomes equal to the lower side distance B. In this way, since a pushing force L from both ends to the center acts on the underside of the tube cover 11A in the extending/contracting movement during the time from the molded state to the shortest contracted state, an upward force M acts on a position near the center of the underside of the bellows 111 of the tube cover 11A.  Accordingly, the upward force M and the own weight N acting on a position near the center of the bellows 111 of the tube cover 11A cancel each other and the nearby position of the center of the bellows 111 of the tube cover 11A does not sag down and it can be kept nearly horizontal.

Title: Control system for memory medium cartridge carrying means in library unit
Inventor: YAMAZAKI ETSURO
IPC: H02P29/00
Filed: 1990-10-18
Abstract: PURPOSE:To compensate for the fluctuation of motor current due to inclination of rail by providing a library unit with a rail inclination sensor and feeding an accessor drive motor with a compensation current in accordance with a detected inclination. CONSTITUTION:Current position of an accessor can be known by the number of tachometer pulse outputted from a motor 35. A state estimating unit 33 estimates the moving speed of the accessor based on a time variation of tacho- pulse outputted from the motor and a current value outputted from an amplifier 32. When an inclination sensor detects an inclination, a compensation current generator 37 generates a compensation current which is then amplified and superposed on an output current from the amplifier 32 and then fed to the motor 35. At that time, polarity of the amplifier 37 is set to cancel the fluctuation of load torque due to the inclination of the rail. According to the constitution, fluctuation of motor drive current for attaining a target speed due to the inclination of the rail is compensated for by means of the compensation current generator 37 resulting in a stable motion control of the accessor.

Title: Facsimile equipment
Inventor: MIURA SHIGEO
IPC: H04N1/00
Filed: 1992-09-25
Abstract: PURPOSE:To prevent the degradation of a picture due to the deviation of the number of data generated in a line by setting the write or read address of a line memory so that it corresponds to the head of one line in the case that this address does not correspond to the head of one line at the time of sending a latch signal. CONSTITUTION:The write or read address of a line memory 4 is checked at the time of sending a latch signal 10; and if the write or read address next to the line memory 4 does not correspond to the head of one line, this address is so set that it corresponds to the head on one line. For example, if only signals whose number is smaller than a prescribed value are inputted because of a momentary break of an input signal SI, the address of the line memory 4 is reset by the latch signal 10. If signals whose number is larger that the prescribed value are inputted, counting-up of the address is stopped to ignore the input. Consequently, the access address of the line memory 4 is set to the head of the line memory 4.

Title: Address control circuit
Inventor: KOMIYA HIROAKI
IPC: G11C29/44
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To provide an address control circuit in which expansion of the circuit scale is prevented and the circuit delay time is less when an IC memory operated at a high speed is tested in a semiconductor test device. SOLUTION: In the semiconductor test device 1, a sequence control section 10 converts an input signal from a tester control CPU into address scramble data and an address clock signal. An address selection control section 20 stores address scramble data based on an address clock signals. The address selection control section 20 outputs address scramble data, that is, an address selecting signal to a 32TO1 selector section 30, and the 32TO1 selector 30 converts an address of a memory IC to an one-dimensional address. Therefore, an address of a memory IC can be directly made in one-dimension, at the time of testing a high speed memory IC, the circuit delay and expansion of circuit scale can be prevented.

Filed: 1989-10-27
Abstract: PURPOSE:To make it hard to receive the effect of a process error by intersecting bit lines between a pair of transistors, and arranging both transistors in the same direction on the layout. CONSTITUTION:Two MOS transistors (e.g. A and B) are aligned and formed on a semiconductor substrate. One (-BLO) of a pair of bit lines (e.g. BLO and -BLO) is connected to the drain region (DA) of the MOS transistor A. The other bit line (BLO) is connected to the gate electrode (GA) of the MOS transistor A. A pair of the bit lines (BLO and -BLO) are intersected between the two transistors (A and B). The other bit line (BLO) is connected to the drain region (DB) of the MOS transistor B. One bit line (-BLO) is connected to the gate electrode (GB) of the MOS transistor B. Thus, one sense amplifier is formed. Even if the position of a mask is deviated in, e.g. the up and down directions, the area of a pair of the transistor regions (e.g. the drain regions DA and DB) is expanded or contracted by the same amount in the same direction. As a result, the difference in characteristics such as unbalance of drain resistances is not generated between the pair of the transistors.

Data for a multiplex channel and subject to gain and orthogonal Hadamard sequence for each channel, two channel data multiplied with the gain and the orthogonal Hadamard sequence are summed in a complex form, a complex multiplier applies complex multiplication to the value summed in the complex form and the outer orthogonal Hadamard sequence in a complex form, and provides outputs of in-phase information and orthogonal phase information. The in- phase information outputted from lots of blocks is summed to the in-phase information and the orthogonal phase information is summed to the orthogonal phase information, and the result is spread by using a spread code in the orthogonal complex spread method for the multiplex channel.
